Definitions
- the present invention relates to harvesting headers, and, more particularly, to transportation of harvesting headers.
- a combine An agricultural harvester known as a “combine” is historically termed such because it combines multiple harvesting functions with a single harvesting unit, such as picking, threshing, separating and cleaning.
- a combine includes a header which removes the crop from a field, and a feeder housing which transports the crop matter into a threshing rotor.
- the threshing rotor rotates within a perforated housing, which may be in the form of adjustable concaves, and performs a threshing operation on the crop to remove the grain.
- Once the grain is threshed it falls through perforations in the concaves onto a grain pan. From the grain pan the grain is cleaned using a cleaning system and is then transported to a grain tank onboard the combine.
- the cleaning system includes a cleaning fan which blows air through oscillating sieves to discharge chaff and other debris toward the rear of the combine.
- Non-grain crop material such as straw from the threshing section proceeds through a straw chopper and out the rear of the combine.
- the combine When the grain tank becomes full, the combine is positioned adjacent a vehicle into which the grain is to be unloaded, such as a semi-trailer, gravity box, straight truck, or the like; and an unloading system on the combine is actuated to transfer the grain into the vehicle.
- harvesting headers are made up of many designs, e.g. corn header, grain header, etc., and typically are available in cutting widths exceeding a typical roadway width. To transport from one location to the next where the cutting width of the harvesting header exceeds the travel width, e.g. roadway width, the harvesting header may be towed transverse to its' cutting width. To facilitate towing in this manner, transport wheels are added to the harvesting header.
- One known type of harvesting header has rigid frame members extending forward from the rear header frame to support the cutter bar.
- a fixed axle or stub axles are added transverse to the cutting width under the rear of the header, as viewed from the towing vehicle.
- At least one steerable wheel can be added under the header closer toward the towed vehicle.
- the at least one steerable wheel typically has a narrow track and is steerable by connection to a towed vehicle via a tongue.
- This at least one steerable wheel is often referred to as a dolly wheel.
- a combine raises the harvesting header, wherein the fixed axle and dolly wheel are attached under the harvesting header.
- Another known harvesting header has a rigid rear frame with forward extending pivotable arms that support the cutter bar to cut the crop.
- additional structure is added to the frame for supporting the axle and dolly wheel as the forward extending frame members are not rigidly fixed to the frame and therefore are not suitable for supporting an axle and dolly wheel.
- Adding additional structure to the frame for supporting transport wheels greatly increases the weight of the harvesting header. This added weight results in higher fuel consumption and additional wear and tear on vehicles and roadways.
- a transport arrangement for an agricultural harvesting header includes a main frame with a forward end located near the towing end of the towing vehicle when viewed in the direction of travel of the towing vehicle and a trailing end located at an end opposite of the forward end, a cutter bar disposed essentially parallel to the main frame and connected to the main frame, a harvesting header centerline disposed between the main frame and the cutter bar, an elongate tongue with a towed end and a distal end, a trailing wheel assembly, e.g.
- an assembly including at least two wheels and an axle or at least one gauge wheel reconfigured to be used as a trailing wheel, connecting to the harvesting header, and the least one dolly wheel e.g. an assembly having a single wheel or a plurality of wheels configured to pivot about the same axis essentially parallel to a direction normal to the surface of the ground or at least one gauge wheel reconfigured to be used as a dolly wheel, connecting rigidly for instance, to the distal end of the elongate tongue, the at least one dolly wheel connecting to the harvesting header, wherein an acute angle is created between the elongate tongue and the direction of travel during transport, and the at least one dolly wheel configured to engage a ground surface behind the cutter bar in a lateral direction towards the main frame.
- a towing vehicle includes a hitch, a towing vehicle center line and a towing end.
- the harvesting header includes a main frame with a forward end located near the towing end of the towing vehicle when viewed in the direction of travel of the towing vehicle and a trailing end located at an end opposite of the forward end, a cutter bar disposed essentially parallel to the main frame and supported by a top deck, a harvesting header centerline disposed between the main frame and the cutter bar, an elongate tongue with a towed end and a distal end, a trailing wheel assembly, e.g.
- an assembly including at least two wheels and an axle or at least one gauge wheel reconfigured to be used as a trailing wheel, connecting to the harvesting header, and the least one dolly wheel e.g. an assembly having a single wheel or a plurality of wheels configured to pivot about the same axis essentially parallel to a direction normal to the surface of the ground or at least one gauge wheel reconfigured to be used as a dolly wheel, connecting rigidly for instance, to the distal end of the elongate tongue, the at least one dolly wheel connecting to the harvesting header, wherein an acute angle is created between the elongate tongue and the direction of travel during transport, and the at least one dolly wheel configured to engage a ground surface behind the cutter bar in a lateral direction towards the main frame.
- a method for transporting a harvesting header includes the steps of: providing a towing vehicle with a hitch, a towing vehicle centerline, and a towing end; providing a harvesting header with a main frame with a forward end located near the towing end of the towing vehicle when viewed in the direction of travel of the towing vehicle and a trailing end being located at an end opposite the forward end, a cutter bar disposed essentially parallel to the main frame and supported by a top deck, and a harvesting header centerline disposed between the main frame and the cutter bar; providing an elongate tongue with a towed end and a distal end; providing a trailing wheel assembly, e.g.
- the at least one dolly wheel rigidly, to the elongate tongue distal end; connecting the at least one dolly wheel to the harvesting header forming an acute angle between the elongate tongue and the direction of travel during transport, the at least one dolly wheel configured to engage a ground surface behind the cutter bar in a lateral direction towards the main header frame; vertically lowering the harvesting header with a device suited for lifting and lowering, such as a combine, to a height sufficient to engage the trailing wheel assembly and the at least one dolly wheel with the at least one ground contact surface; and pivotably connecting the elongate tongue towed end to a towing vehicle, wherein the towing vehicle centerline may be disposed essentially colinear to the harvesting header centerline.
- An advantage of the present invention is a device that allows gauge wheels to be repositioned to serve as transport wheel(s).
- Another advantage is weight reduction of the harvesting header through elimination of additional frame members used to support transport wheel(s).
- Another advantage yet is allowing the harvesting header and a towing vehicle to share essentially the same centerline when in a transport condition.
- FIG. 1 is schematic top view of an embodiment of a system for transporting a harvesting header
- FIG. 2 is a schematic side view representing the system in FIG. 1 for transporting a harvesting header
- FIG. 3 is a schematic view of cross section 3 - 3 as shown in FIG. 2 ;
- FIG. 4 is a flowchart of an embodiment of a method of the present invention for transporting a harvesting header.
- FIG. 1 there is shown a system 100 for transporting a harvesting header which generally includes a towing vehicle 110 and a harvesting header 120 wherein a centerline of the towing vehicle 110 may be disposed essentially colinear to a centerline of the harvesting header 120 .
- Towing vehicle 110 as shown in the illustrated embodiment is assumed to be an agricultural tractor but may also be any suitable form of vehicle used for towing.
- the towing vehicle 110 includes a towing vehicle centerline 112 disposed essentially longitudinally to a direction of travel 114 , a rear or towing end 116 disposed essentially perpendicular to the direction of travel 114 and being located at the towing end 116 of the towing vehicle 110 , and a hitch 118 located essentially on the centerline 112 and at the towing end 116 of the towing vehicle 110 .
- Harvesting header 120 generally includes a main frame 122 .
- the harvesting header 120 is shown in a transport orientation with the main frame 122 disposed essentially longitudinally to the towing vehicle 110 direction of travel 114 .
- the harvesting header 120 further has a forward end 122 a and a trailing end 122 b relative to the direction of travel 114 .
- the main frame 122 may include a discharge outlet and connection point 124 for a feeder housing of a combine (i.e., traction unit, not shown).
- a trailing wheel assembly 126 is connected to the harvesting header 120 at a location near the trailing end 122 b .
- a harvesting header includes a longitudinally extending centerline 128 disposed essentially parallel with the towing vehicle 110 direction of travel 114 and located approximately equidistant between the main frame 122 and a cutter bar 130 .
- a top deck 132 such as a draper belt or sheet metal for an auger, is configured for guiding a cut crop to the connection point 124 and is further adapted to support cutter bar 130 .
- At least one dolly wheel 134 is attached to the harvesting header 120 at a location near the forward end 122 a and laterally disposed from the centerline 128 towards the main frame 122 thereby positioning the at least one dolly wheel 134 closer to the main frame 122 and requiring less additional structural material.
- An elongate tongue 136 is attached to the at least one dolly wheel 134 forming an acute angle ⁇ between the elongate tongue 136 and the direction of travel 114 during transport.
- Examples of connections between the elongate tongue 136 and the at least one dolly wheel 134 include but are not limited to: pin, bolt, screw, and weld joints.
- the connection between the elongate tongue 136 and dolly wheel 134 can also be supported and/or reinforced as appropriate, such as with gussets, plates, brackets, etc.
- the elongate tongue 136 may be further adapted to connect to the hitch 118 of the towing vehicle 110 .
- the acute angle ⁇ may be any angle that is greater than 0° and less than 90°, preferably at an angle between 0° and 30°. In the illustrated embodiment, the angle ⁇ is approximately 15°.
- An acute angle ⁇ greater than 0° and less than 90° may provide that the towing vehicle 110 and the harvesting header 120 share essentially the same centerline. Shifting the at least one dolly wheel 134 laterally closer to the main frame 122 will not negatively affect the at least one dolly wheel 134 position relative to a center of gravity of the harvesting header 120 as most of the mass of the harvesting header 120 is along the main frame 122 .
- the equation to determine the acute angle ⁇ needed to essentially provide the same centerline between the towing vehicle 110 and the harvesting header 120 is:
- ⁇ sin - 1 ⁇ ( DW O ET L )
- ⁇ is an angle formed between the elongate tongue 136 and the direction of travel 114 during road transport
- DWO is a lateral offset of at least one dolly wheel 134 from the harvesting header centerline 128
- ETL is the length of the elongate tongue 136 from the at least one dolly wheel 134 to an opposite end configured to attach to the hitch 118 .
- connection between the elongate tongue 136 and the at least one dolly wheel 134 may provide an adjustable or a fixed acute angle.
- the acute angle ⁇ may be adjustable with a configurable connection between the elongate tongue and the at least one dolly wheel 134 to provide any angle that is greater than 0° and less than 90°.
- the acute angle may also be fixed with a rigid connection between the elongate tongue and the at least one dolly wheel 134 configured at a preset angle greater than 0° and less than 90°.
- the rigid connection may further allow the elongate tongue 136 to have freedom to move/rotate about an axis perpendicular to both the axis of rotation of the at least one dolly wheel 134 and either the direction of travel 114 or the length of the elongate tongue 136 to allow for movement of the elongate tongue 136 in upward and downward directions with respect to the forward end 122 a of the main frame 122 as hills/valleys are traversed.
- FIG. 2 a side view is shown of the embodiment of the harvesting header 120 in FIG. 1 .
- the at least one dolly wheel 134 attaches to the harvesting header 120 near the forward end 122 a .
- the trailing wheel assembly 126 is attached the harvesting header 120 near the trailing end 122 b.
- FIG. 3 there is shown a cross section view of the at least one dolly wheel 134 attached to the elongate tongue 136 .
- the attachment may allow or prevent disassembly of the at least one dolly wheel 134 from the elongate tongue 136 .
- the structures that make up the attachment may include but are not limited to: pin, bolt, screw, and weld joints.
- the attachment of the at least one dolly wheel 134 attached to the elongate tongue 136 results in an acute angle ⁇ being created between the elongate tongue 136 and the forward end 122 a of the main frame 122 when the at least one dolly wheel 134 and the elongate tongue 136 are attached to the harvesting header 120 .
- the attachment may allow for adjustment thereby provide an acute angle ⁇ of greater than 0° and less than 90°.
- the at least one dolly wheel 134 may include a single wheel or a plurality of wheels.
- the method generally includes the steps of vertically raising the harvesting header to a height sufficient to mount a trailing wheel assembly and at least one dolly wheel (step 402 ), connecting the trailing wheel assembly to the harvesting header (step 404 ), connecting rigidly for instance the at least one dolly wheel to the elongate tongue (step 406 ), connecting the at least one dolly wheel to the harvesting header (step 408 ), vertically lowering the harvesting header until the at least one trailing wheel and the at least one dolly wheel engage with the at least one ground contact surface (step 410 ), and then pivotably connecting the elongate tongue towed end to the hitch of the towing vehicle (step 412 ).
